I've emailed quaife to see what they say. I'm still worried that it's going to turn out that I have an open diff and all this time I've been wrong ha ha. Last time I was at Bedford it was wet and I was powersliding out of that corner (I got told off by the Marshall) I assume I can get stiffer springs. I've never adjusted the rear shocks. Dad did say that he thought my rear looked a bit bouncy. Maybe the shocks are shot.

Aha - so you were serious that you are not sure that it's a Quaife! Good luck! I'd be really surprised to learn that your car doesn't have a proper diff.

Most tired shocks leak oil and it's often obvious. I've had a gas shock that lost pressure. I had to compare its action to confirm that it was not good though. The car started pitching, so I suspected it was duff, but it was not oily...

Right.
it's _definitely_ a Quaife.
the endoscope was a complete waste of time. but the tiny little torch on it meant I could see the pinion gears inside the diff like
so I'm just left with too think an ARB on the back
or the shocks are setup wrong.
or something else.
I _REALLY_ don't want to have to swap the rear ARB. it's a massive ballache
